Adding fuel to the fire
I'm new here, but I'm no stranger to this debate.
Like RNB65, I'm unimpressed by this "ARs are unreliable" jazz. I've put close to 1,000 rounds through my mid-length RRA LAR-15, most of it Wolf (because I'm a poor college student), and I've had ONE feed problem. This came after firing nearly 400 rounds of Wolf 62gr JHP over the course of three extremely dusty and abusive days, and not having a chance to clean it. The chamber got kind of gunky, and the round had to be forward-assisted in. I did a quick-clean and fired another 100 rounds with nary a problem.
On the flip side, I have been unimpressed with the AK-47 (although admittedly I have only shot cheap Romanian semis). Call me crazy, but I like my bullets to go where I tell them to... Basically, the whole thing felt cheap (because it was) and its ergonomics weren't natural for a big American man like myself.
Neither gun is a very complicated machine, when you get right down to it, and learning the ins and outs of their functionality should only take a couple hours of fiddling, which is fun anyway.
